rounds with right- and left-hand feed. It
is recoil-operated, link-belt-fed, and air-
cooled. Upgrades have increased product
durability and Soldier safety by moving
the headspace and timing adjustment
task above the operator level.
" e M2A1 s xed headspace and tim-
ing enhancement resolve the number
one safety issue for Soldiers operating
the weapon system," said Laura Battista,
M2 Product Director for PEO Soldier s
Product Manager Crew Served Weap-
ons. " e M2A1 addresses this concern
by moving the adjustment task above
the operator level, thereby minimizing
the risk of malfunctions or injuries in
the eld. is also frees up vital Soldier
training time for other critical tasks."
A more durable barrel extension is also
a signi cant M2A1 enhancement. " e
barrel extension is machined from
maraging steel, thus increasing the
durability and reducing part breakage
over the current M2," said Robert
Sulzbach, M2A1 Project O cer at
ARDEC s Weapons and Software
Engineering Center. "Maraging steel is
a strong, tough, carbon-free iron alloy,
which contains nickel, cobalt, titanium,
and molybdenum. e steel is heat-
treated to an extremely high tensile
strength, resulting in longer life and
greater durability for the component."
LTC omas Ryan, Product Man-
ager Crew Served Weapons, said, " e
upgrades we ve incorporated will keep
this weapon relevant well into the future."

UNMANNED TEAMING
"As operations picked up in Iraq and the
number of unmanned aircraft systems
[UAS] was reaching critical mass, the
Army found a compelling need to quickly
get direct viewing of UAS sensor data into
the Apache helicopter to greatly enhance
its capability," said Layne Merritt, Chief
Engineer, Aviation Development Direc-
torate, Aviation and Missile Research,
Development, and Engineering Cen-
ter (AMRDEC). According to Merritt,
manned-unmanned teaming between
Army UAS and rotary-wing attack and
scout platforms has been an objective since
SAFETY ISSUE RESOLVED
The M2A1 .50-caliber machine gun is an enhancement to the .50-caliber
M2, with a modified barrel, barrel extension, barrel support, barrel
